Manually install an SSL certificate on my Cisco ASA 5500 VPN/Firewall

Find the directory on your server where certificate and key files are stored, then upload your intermediate certificate (gd_bundle.crt or similar) and primary certificate (.crt file with randomized name) into that folder.

Launch the Cisco ASDM (Adaptive Security Device Manager).

In the list of icons near the top of the screen, click Configuration.

On the left hand sidebar, click Remote Access VPN.

In the new panel on the left, click to expand Certificate Management and click CA Certificates.

On the right-hand side of the main panel, click Add.

For the Trustpoint Name, simply enter a name to easily identify your intermediate certificate at a later date.
